[PATCH 0/2] Fix tuning on eUSB2 repeater

Posted by Luca Weiss 3 months, 3 weeks ago

Update the dt-bindings to remove the 'default' tuning values, since they
depend on the PMIC and are not guaranteed to be the same.

And add a fix into the driver to not zero-out all tuning registers if
they are not specified in the "init sequence", since zero is not the
reset value for most parameter and will lead to very unexpected tuning.
